[jira] [Resolved] (HBASE-5853) java.lang.RuntimeException:
readObject can't find class org.apache.hadoop.hdfs.protocol.HdfsFileStatus
[ https://issues.apache.org/jira/browse/HBASE-5853?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Lars Hofhansl resolved HBASE-5853.
----------------------------------
Resolution: Invalid
I verified that org.apache.hadoop.hdfs.protocol.HdfsFileStatus still exists in Hadoop trunk.
So I am pretty sure this is a setup issue.
Please re-open if this is not correct (in which case I apologize in advance).
